woah chill out man, I'm obviously joking around. I just sincerely don't get the combination of the words "used to could", it seems like "used to be able" would be easier to think of mentally and so I didn't see how "used to could" would evolve.

Oh don't worry about it. I wasn't trying to sound pissy. That's what I dislike about text mediums. If we were talking we'd come across totally different to each other. I mean I wont lie, I was being serious, but I was just trying to get a point across.
